On PFSense I can enter a MAC address for each virtual interface, but when I bring the interfaces up the second interface to activate overwrites the MAC of the first virtual interface on the same physical network card. It's a single line in the 'interfaces' file to set a different MAC on one of the virtual interfaces and everything works as expected. If I use the same MAC on both VLAN interfaces, only the last one to do DHCP gets network access. The problem: On the WAN side, both VLAN's need to use a different MAC address. From the LAN side, both need to be accessible for IPTV to work. One VLAN is used for Internet, the other is used for IPTV. The situation: the link to my ISP is a trunked connection with 2 VLAN's. Sadly, I have to say the issue that I had 2 years ago still isn't resolved and as a result it's impossible to run PFSense as a router for my network. It's is used as a NAT router for a gigabit fiber connection, as an IGMP proxy for IPTV, as a DHCP server and caching DNS server. My router is build around an Asus P9D-I with integrated i210 NIC's, a Celeron CPU and 4GB of ECC RAM. So yesterday, wanting to get something up and running quickly, I decided to give PFSense another go.

When I originally set up this router, about 2 years ago, I had a look at PFSense and couldn't get it to work correctly on my network due to a bug (you could arguably call it a missing feature) in PFSense. I had a little disaster with my Linux-based router yesterday (the root disk died on me and idiot me didn't have a backup) leaving me without internet or TV.
